busybox

I have occasionally installed cloud-init package in Ubuntu, which blocks me from booting. Neither recovery mode works. Because cloud-init installed some upstart job configuration. So I want to enter into busybox to remove /etc/init/cloud-init*.conf, but it seems like no way to do it. I can press Ctrl+Alt+SysRq which brings on a rough hack menu, but there is no busybox option. So is it possible? My CDROM is broken so I can't use Live CD too.
